8 The plot of NH2 vs. % Al will be a straight line. To fix the position of a straight line it is necessary t least three points. The way to do this is to find when % AL=0,%AI - 25,%AI -50. %Al = 75 and when % Al = 100. All these points should lie on the same straight line 2. Sample data for this experiment. Fill in the blanks in the data and make the indicated calculation 1...

Chame nsead tu age 06-17 Experiment 8: Molar Mass of a Volatile Liquid Purpose To determine the molar mass of a pure substance we need to find out (a) the number of moles in a given sample, and (b) the mass of the same sample. Molar mass is then: mass divided by moles Introduction Using the ideal gas equation, PV= nRT, we can determine the number of moles (n) of gas or vapor under measured conditions of pressure (P), volume...
